Timonacic or thioproline (4-Thiazolidinecarboxylic acid) is the product of condensation between cysteine and formaldehyde. Dietary timonacic slows the aging process in mammals and prolongs their life span. It exerts antioxidant and antineoplastic actions however its mechanism of action is elusive. Timonacic (brand names Heparegen or Arbitol) is used for the treatment of liver diseases.

CNS Activity
